Suddenly, the dog starts to snort loudly and inhales sharply—a moment of alarm for many owners. However, what appears to be a seizure is usually harmless. PETBOOK explains what exactly is behind reverse sneezing, its causes, and why certain dog breeds are particularly prone to it.
The phenomenon usually occurs quite suddenly and lasts only a few seconds—but it can seem quite alarming. With a tense body, stiff neck, and wheezing sounds, the so-called reverse sneezing in dogs is familiar to many owners. But how does it happen in the first place?
Overview
What is Reverse Sneezing?
Reverse sneezing, also known as “inspiratory paroxysmal respiration reflex” or “reverse sneezing,” is, as the name suggests, a kind of inverted sneeze. Instead of expelling air, the dog suddenly inhales air through the nose. This produces wheezing, snoring, or gasping sounds that often sound like the animal is having breathing problems. Like normal sneezing, it is an automatic reflex triggered by the body itself. Usually, the dogs are tense, stand still, and pull their lips back—but afterward, the animal appears completely normal again.
Reverse sneezing occurs mainly in dogs. While a similar behavior can occasionally be observed in cats, it is much less common. Other pets like birds, hamsters, or rabbits have a different nasal-pharyngeal anatomy—so reverse sneezing does not occur in them.
Possible Causes
Reverse sneezing is triggered by irritations in the throat or palate. The exact causes are not yet fully understood, but there are several factors that can promote the reflex. Dust, pollen, perfume, or drafts can be triggers. A sudden pull on the collar, sudden excitement, or eating or drinking too quickly can also trigger the reflex.
Breeds of Dogs Particularly Affected by Reverse Sneezing
While all dog breeds can be affected by reverse sneezing, some are particularly prone to it. Small breeds and dogs with short snouts and narrow airways are more likely to experience this reflex because they have a shortened nasal-pharyngeal space and an enlarged soft palate. These include
- Pugs,
- Boxers, and
- French Bulldogs.1
When to See a Vet?
In rare cases, the loud snorting can also indicate serious conditions such as respiratory diseases, allergies, or infections. It’s important to closely observe the dog: How often does reverse sneezing occur? If other symptoms like coughing, fever, or even shortness of breath appear, the cause should be clarified by a veterinarian. In older dogs, frequent reverse sneezing can also be a warning signal.

How to Support Your Dog
If your dog starts reverse sneezing, it’s important to stay calm to avoid stressing the animal further. Petting and speaking softly can also help calm your four-legged friend. Observe how your dog behaves, offer a treat, or support them with a gentle massage of the chest or larynx. 2
